The Intel Pentium 3805U is an entry-level CPU used mostly in ultrabooks and small devices from 11-inch diagonal or greater. The chip is based on the Broadwell architecture continuing the Tick-Tock with “Tick”. It offers smaller die size and improved energy over its Haswell counterpart efficiency thanks to the 14nm FinFET manufacturing process.
However, it’s clocked at 1.9 GHz without the so-called Turbo or Hyper-Threading features having two physical cores. It’s also part of the ULV (ultra-low voltage) lineup so the TDP here is 15W making it suitable for energy-efficient notebooks and ultrabooks for office work and multimedia. It also supports DDR3(L)-1600 dual-channel memory controller and can be paired with up to 16GB of RAM.
The integrated graphics chip is also based on the Broadwell generation – Intel HD Graphics (Broadwell) with 12 EU (Execution Units) clocked at 100 – 800 MHz supporting DirectX 11.2, OpenCL 1.3/2.0 and OpenGL 4.3.
